54 Troubleshooting
Too much paper loaded. Make sure that the paper stack does not exceed the paper support load limit.
However, proper feeding of paper may not be possible at this maximum capacity
depending on the type of paper or environmental conditions (either very high or
low temperature and humidity).
In such cases, reduce the sheets of paper you load at a time to around half of
the paper support load limit.
For details on loading paper, see “Loading Paper” on page 15.
Foreign object in the Rear Tray. Make sure that there are no foreign objects in the Rear Tray.
Envelopes not prepared nor loaded
properly.
z When printing on envelopes, see “Loading Envelopes” on page 17, and
prepare the envelopes before printing.
Once you have prepared the envelopes, load them in the machine in portrait
orientation. If the envelopes are placed in landscape orientation, they will not
feed properly.
